TUBE PASTE DISPENSER Filed June 29, 1932 2 Sheets-Sheet 2 Inventor 68076 U 6 0w??? Patented July 4, 1933 The present invention relates to a tube paste dispenser and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character embodying a novel construction, combination and arrangement of parts through the medium of which substantially all of the contents of a collapsible tube may be ejected as desired in a convenient manner.

Other objects of the invention are to providea tube paste dispenser of the aforementioned character which will be simple in construction', strong, durable, efficient and reliable in use, compact, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further obiects and advantages of the mvention will become apparent from a study of the fol- 29 lowing specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein Figure 1 is a view in front elevation of a tube paste dispenser constructed in accordance with the present invention.

upper and lower plates 6 and 7, respectively.

Spaced, vertical guide rods 8 and a spirally grooved shaft 9 extend between the plates 6 and Journaled horizontally in the housing 1 above the plate 6 is a drive shaft 10 which is operatively connected to the shaft 9 by beveled gears 11. One end of the shaft 10 projects from the housing 1 and has fixed thereon a hand knob or wheel 12.

The reference numeral 13 designates a horizontally disposed, substantially U-shaped frame which is mounted for vertical, movement in the housing 1 on the guide rods 8 and the shaft 9. One end portion of the frame 13 is bifurcated, as at let, to provide a space for the accommodation of a worm gear 15 which is operatively connected to the shaft 9 for actuation by said shaft through the medium of a key or lug 16 which is engaged in the spiral groove of the shaft. This key or lug is designated by the reference numeral 16.

J ournaled horizontally in said one end portion of the frame 13 is a sleeve 17 having formed integrally therewith a worm gear 18 which is in mesh with the worm gear 15. A diametrically extending pin 19 is mounted in the sleeve 17 for a purpose to be presently set forth.

Journalled horizontally in the frame 13 is a slidably removable spool 20 having a slot 21 extending longitudinally thereinto from one end thereof. On the other end of the spool 20 is fixed a knob 22. When in operative position, said one end of the spool 20 is engaged in the sleeve 17, the slot 21 receiving the pin 19 for connecting said spool to the sleeve for actuation thereby. The slot 21 also receives the closed end portion of the collapsible tube, one of which is designated by the reference numeral 23.

The reference numeral 24; designates a tapered nozzle having a reduced neck 25 thereon which is threadedly engaged in an opening provided therefor in the plate 7. The neck 25 is also internally threaded for rece1ving the neck 26 of the tube 23. The outlet of the passage in the nozzle 2% i s substan tially slot-shaped, as at 27 (see Figure 8). The nozzle 2% depends from the housing 1 through an opening 29 provided therefor in the bottom of said housing.

If desired, a spring motor 30 of substantially conventional construction may be mounted in the upper portion of the housing 1 for actuating the shaft 9. The spring motor 30 is operatively connected to the shaft 9 by gears 31 in which is included a manually operable reversing gear permitting the shaft to be actuated in opposite directions to raise or lower the frame 13 and to rotate the spool in opposite directions. The reference numeral32 designates a winding key for the motor 30 which is insertable through an opening provided therefor in the top of the hous- Tn ;use, the frame 13 is raised to the upper portion of the housing 1 and the tube 23 is inserted in said housing.- The neck 26 of the tube 23 is threaded into the neck of the nozzle 24 and the closed end portion of said tube 23, which is now uppermost, is inserted inthe slot 21 of the spool 20. Then, the shaft 9 is actuated, either by the drive shaft 10 or the spring motor 30, to rotate the spool 20 for winding the tube 23 thereon, as illustrated in Figure 2 of the drawings, thus ejecting the contents of said tube 23. At the same time, the frame 13 is moved downwardly on the guide rods 8 by reason of the engagement of the-key or lug 16 in the spiralled groove of the shaft 9. To raise the frame 13, the direction of rotation of the shaft 9 is reversed. A suitable cut-0E valve .(notshown) may be provided in the nozzle 24 for controlling the discharge of the paste, particularly when the spring motor is being used. a a

It is believed that the many advantages of a tube paste dispenser constructed in accordance with the present invention will be readily understood, and although the preferred embodiments of the invention are as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
